Smartphone-Based Hearing Self-Assessment System Using Hearing Aids With Fast Audiometry Method

The objective measurement of the demo system verifies the precision of the sound level within a variation less than 0.5 dB HL for all six frequency bands. The subjective test with 20 samples with different levels of hearing loss in a sound-proof booth indicates that the SHSA system has an average difference of less than 6 dB HL for different hearing-loss severity, and is capable of saving more than 50% hearing test time on average compared to the conventional hearing test.
